while preparing my packaging of Tails' OpenPGP Applet (ITP #756404), it was
pointed to me that there were issues on images files shipped with it : they
where licensed using CC-BY-SA 2.0, which is not DFSG-compliant. They seemed
indeed derived from icons using an old tango theme, which were indeed licensed
CC-BY-SA 2.0 at the time.
I saw that on my Sid system, several packages have the same issue :
~$ rgrep -rl 'by-sa/2\.0' /usr/share/icons/*/scalable |xargs dlocate --package-only
There may be more, since it only reports the packages I have installed.
It doesn't seem to be dual-licensing, judging from the content of the svg files
So, I asked on debian-devel but received very few responses, mostly
inconclusives or saying we should allow CC-BY-SA 2.0 in debian  
This is not an issue in the package I work on anymore, since I could remake the
icons and include them upstream. However, I think it's best to track this issue
and maybe clarify once and for all what to do with CC-BY-SA 2.0 images.
Currently, I see the following options :
- convincing upstream to relicense the files using a later (>= 3.0) version of the license, which, as I found out, can be difficult
- removing or replacing the files
- decide that CC-BY-SA 2.0 is OK after all.
